Poul Anderson (1926–2001) grew up bilingual in a Danish American family. After discovering science fiction fandom and earning a physics degree at the University of Minnesota, he found writing science fiction more satisfactory. Admired for his “hard” science fiction, mysteries, historical novels, and “fantasy with rivets,” he also excelled in humor. He was the guest of honor at the 1959 World Science Fiction Convention and at many similar events, including the 1998 Contact Japan 3 and the 1999 Strannik Conference in Saint Petersburg, Russia. Besides winning the Hugo and Nebula Awards, he has received the Gandalf, Seiun, and Strannik, or “Wanderer,” Awards. A founder of the Science Fiction & Fantasy Writers of America, he became a Grand Master, and was inducted into the Science Fiction and Fantasy Hall of Fame.
 
In 1952 he met Karen Kruse; they married in Berkeley, California, where their daughter, Astrid, was born, and they later lived in Orinda, California. Astrid and her husband, science fiction author Greg Bear, now live with their family outside Seattle.
 
Karen Anderson (b. 1932) is both a science fiction fan and a founder of the Science Fiction & Fantasy Writers of America. She graduated from high school in Maryland and worked as a military cartographer to pay for both her attendance at the 1952 World Science Fiction Convention and the academic year 1952–53, which she spent as a drama major. Correspondence with Poul Anderson convinced her that the life she wanted was in science fiction, not on the stage, and she and Anderson later married.
 
Karen Anderson’s solo work comprises verse and short fiction. She brought many skills to assist Poul Anderson in writing his novels: proofreading, research, languages, mapping, story planning, and collecting material for future works. Discussions led to early shared bylines; after visiting Hadrian’s Wall, Karen Anderson put a year’s research and plotting—plus verses of her own—into his hands for The King of Ys.
 
Karen Anderson now lives half an hour’s drive from the Los Angeles Science Fantasy Society’s clubhouse.
